nvhdmi_chmap_cea_alloc_validate_get_type calls itself recursively using chmap ops causing the double fault. Fixed by adding the default validate_get_type handling inside nvdia validate_get_type handler.

The commit [d507941b: ALSA: pcm: Correct PCM BUG error message] made the warning prefix back to "BUG:" due to its previous wrong prefix. But a kernel message containing "BUG:" seems taken as an Oops message wrongly by some brain-dead daemons, and it annoys users in the end. Instead of teaching daemons, change the string again to a more reasonable one.

There is an implicit rule to map between pin NID and port number on Intel HDMI/DP codec: the mapping is fixed only for NID 0x05, 0x06 and 0x07. For avoiding the possible memory corruption, add a sanity check for the NID value and splat WARN_ON() for invalid accesses. Signed-off-by: Takashi Iwai <tiwai@suse.de>

In dice interface, two blocks of register are accessible via IEEE 1394 asynchronous transaction to represent the number of supported isochronous streams and the number of quadlets for stream information. Current ALSA dice driver uses array with 'unsigned int' element for temporary cache of these information. But using structure is preferable for begin easily comprehensible. This commit applies a local structure for this aim. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

The current Intel HDMI codec driver supports only three fixed ports from port B to port D. However, i915 driver may assign a DP on other ports, e.g. port A, when no eDP is used. This incompatibility is caught later at pin_nid_to_pin_index() and results in a warning message like "HDMI: pin nid 4 not registered" at each time. This patch filters out such invalid events beforehand, so that the kernel won't be too grumbling.

Some models reduce the number of available isochronous streams for higher sampling transfer frequency. Such models bring an issue about how to add PCM substreams. When at lower sampling transfer frequency, the models reports whole available streams, thus this driver can add enough number of PCM substreams at probing time. On the other hand, at higher sampling transfer frequency, this driver can just add reduced number of PCM substreams. After probed, even if the sampling transfer frequency is changed to lower rate, fewer PCM substreams are actually available. This is inconvenience. For the reason, this commit adds a list so that this driver assume models on the list to have two pairs of PCM substreams. This list keeps the name of model in which the number of available streams differs depending on sampling transfer frequency.

In former commits, ALSA dice driver can handle available isochronous streams. This commit adds support for several PCM substreams on the streams. The additional PCM substreams are available via another ALSA PCM character devices so that one ALSA PCM application can handle them without cumbersome operations. For example, two PCM substreams are available on each stream, two ALSA character devices are added for them. In configuration space of alsa-lib, it's represented with 'hw:0,0' and 'hw:0,1'. The PCM substreams are constraint to parameters of the corresponding streams. If the PCM substreams are unavailable for some reasons, open(2) to ALSA PCM character device returns error and reports ENXIO.

This commit enables ALSA dice driver to handle whole available streams. In Dice, certain registers represent the number of available streams at current sampling transfer frequency for both directions. The parameters of each stream are represented in a block of register. This block is aligned sequentially. These streams start simultaneously by writing enable bit to a register. This commit operates these registers when starting/stopping streams.

Currently ALSA dice driver handles a pair of isochronous resources for IEC 61883-1/6 packet streaming. While, according to some documents about ASICs named as 'Dice', several isochronous streams are available. Here, I start to describe ASICs produced under 'Dice' name. * Dice II (designed by wavefront semiconductor, including TCAT's IP) * STD (with limited functionality of DTCP) * CP (with full functionality of DTCP) * TCD2210/2210-E (so-called 'Dice Mini') * TCD2220/2220-E (so-called 'Dice Jr.') * TCD3070-CH (so-called 'Dice III') Some documents are public and we can see hardware design of them. We can find some articles about hardware internal register definitions (not registers exported to IEEE 1394 bus). * DICE II User Guide * http://www.tctechnologies.tc/archive/downloads/dice_ii_user_guide.pdf * 6.1 AVS Audio Receivers * Table 6.1: AVS Audio Receiver Memory Map * ARX1-ARX4 * 6.2 AVS Audio Transmitters * Table 6.2: AVS Audio Transmitter Memory Map * ATX1, ATX2 * TCD22xx User Guide * http://www.tctechnologies.tc/downloads/tcd22xx_user_guide.pdf * 6.1 AVS Audio Receivers * Table 66: AVS Audio Receiver Memory Map * ARX1, ARX2 * 6/2 AVS Audio Transmitters * Table 67: AVS Audio Transmitter Memory Map * ATX1, ATX2 * DICE III * http://www.tctechnologies.tc/downloads/TCD3070-CH.pdf * Dual stream 63 channel transmitter/receiver For Dice II and TCD22xx series, maximum 16 data channels are transferred in an AMDTP packet, while for Dice III, maximum 32 data channels are transferred. According to the design of the series of these ASICs, this commit allows this driver to handle additional set of isochronous resources. For practical reason, two pair of isochronous resources are added. As of this commit, this driver still use a pair of the first isochronous resources.

rawmidi devices expose the card number via IOCTLs, which allows to find the corresponding device in sysfs. The sequencer provides no identifing data. Chromium works around this issue by scanning rawmidi as well as sequencer devices and matching them by using assumtions, how the kernel register sequencer devices. This changes adds support for exposing the card number for kernel clients as well as the PID for user client. The minor of the API version is changed to distinguish between the zero initialised reserved field and card number 0.

HD-audio driver has a mechanism to trigger the runtime resume automatically at accessing the verbs. This auto-resume, however, causes the mutex deadlock when invoked from the regmap handler since the regmap keeps the mutex while auto-resuming. For avoiding that, there is some tricky check in the HDA regmap handler to return -EAGAIN error to back-off when the codec is powered down. Then the caller of regmap r/w will retry after properly turning on the codec power. This works in most cases, but there seems a slight race between the codec power check and the actual on-demand auto-resume trigger. This resulted in the lockdep splat, eventually leading to a real deadlock. This patch tries to address the race window by getting the runtime PM refcount at the check time using pm_runtime_get_if_in_use(). With this call, we can keep the power on only when the codec has been already turned on, and back off if not. For keeping the code consistency, the code touching the runtime PM is stored in hdac_device.c although it's used only locally in hdac_regmap.c.

Merge tag 'asoc-fix-v4.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v4.5 This is far too big a set of fixes for this late in the release cycle but the overwhelming bulk is essentially the same simple fix from Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace interface where drivers were accessing things using the wrong element in a union which worked OK on 32 bit platforms as the correct element happened to be aligned the same way but with 64 bit platforms ABIs are different and the two members of the union are laid out in different places. They aren't all tagged to stable since some of these chips have vanishingly little chance of being used in 64 bit systems. The other changes are: - A fix for Qualcomm devices to work on big endian systems. The original change is actually correct but triggered a bug in regmap which is too invasive to fix for this cycle and can be worked around by just letting regmap pick the default. - A fix for the Samsung I2S driver locking which wasn't using IRQ safe spinlocks when it needed to. - A fix for the new Intel Sky Lake driver forgetting that C pointer arithmetic takes the type of the pointer into consideration. - A revert of a change to the FSL SSI driver that broke some systems. - A fix for the cleanup path of the wm9713 driver. - A fix for some incorrect register definitions in the ADAU17x1 driver that caused misclocking in some configurations. - A fix for the tracepoints for jack detection to avoid using an internal field of the core jack structure which is no longer present in all configurations. - A fix for another of the new Intel drivers which tried to write to a string literal.

Defer to register acomp eld notifier until hdmi audio driver is fully ready. After registering eld notifier, gfx driver can use this callback function to notify audio driver the monitor connection event. However this action may happen when audio driver is adding the pins or doing other initialization. This is not always safe, however. For example, using per_pin->lock before the lock is initialized. Let's register the eld notifier after the initialization is done. Signed-off-by: Libin Yang <libin.yang@linux.intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
